A distance between points A and B is measured and recorded as 345.67 ft, using a tape that has a certified standard length of 100.02 ft. What is the "true" distance between A and B? (Assume normal tension is used, and no temperature correction is required.)
At A, the pipe diameter is 24 in and the pressure is 45 psi. At B, the pipe diameter is 12 in and the pressure is 50 psi. Point B is 3 f t lower than A. Find the flow rate if the pump puts 22 hp (16 kW) in to the flow. Neglect head losses.
From a videotape, it was observed that a player kicked a football 126 {\rm ft} during a measured time of 3 seconds. Determine the initial speed of the ball and the angle(theta) at which it was kicked
A compressor installed at a whalf (for loading container ships) is able to provide 6 bar.g pressure into the pressure reciever. The compressor is moved to a site that is 5000 ft above sea level (atmospheric pressure 0.85 bar.a
A refrigerator removes 1.5 kW from the cold space at -10?C, using 750 W of power input while it rejects heat to the kitchen at 25?C. Find the rate of irreversibility.
A 100ft tape is calibrated at 68 degrees F, fully supported with 15 Ibs of tension and found to be 99.987 ft long. Is this tape is used fully supported with 15 Ibs of tension at 86 degrees F to measure a distance that is recorded as 136.48 ft,
An emission control system for a new car costs $800 and reduces NO_x emissions from 0.4 g/mile to 0.23 g/mile. Assume the car is driven 10000 miles per year, and the life of the emissions control system is 11 years with zero scrap value.
Calculate the minimum flow rate (m^3/hr) of river water needed to acheive pre cooling hot, pasteurized liquid prodcut assuming that 10% heat is lost to the surroundings during exchange and that the water temp after cooling should not exceed 25 deg..
The thermocouple effective diameter is 2 mm and it is exposed to a convection environment at 20? with h = 125 W/m2 · ?C. The convection coefficient to the solid is 15 W/m2 · ?C. The thermocouple indicates a solid temperature of 125?C. Calculate the t..
A slurry containing 20 percent by weight of limestone (CaCO 3 ) is processes to separate pure dry limestone from water. If feed rate is 2000kg/h, how much CaCO 3 is produced per hour?
The force-couple system consists of the force R = 250i + 360j - 400k N and the couple-vector CR = 1200i+750j+560k N·m. Determine the equivalent wrench and find the coordinates of the point where the axis of the wrench crosses the xy-plane.
For simplicity assume the catapult consists of the piston-cylinder geometry (with the piston as the projectile) and that it is positioned horizontally. The steam initially occupies a volume of 1 liter at a pressure of 200 kpa.
An incompressible fluid flows horizontally in the x-y plane with a velocity given by v = 20 (z/h)^(1/3),where z and h are in meters and h is a constant.
